Raising the carrier from 70W to 150W means about gaining 1/2 of an S-point
on the receiving end. 1 S-point is 6 dB increase in power, which is
quadrupling it, as if you increased from 70 to 280 W carrier. Doubling the
power is 3 dB, which is a half S-point.
It's not worth the effort.

My 32V-2 only makes 70 watts of carrier. (low voltage selected)
I have a good condition Collins 30S-1 that I normally use for SSB.
If the power is kept down to about 150 watts of carrier, could I drive the
amp w/ the 32V-2?
My first homebrew amp is under construction, but until it is ready, I am
hoping to find a temporary
